CSEF · 2002 Earth Sciences/ Planetary Sciences/ Physical Environments

Carter E. Greenbaum · Tarbut V' Torah Community Day School, Irvine

Overview

Objectives/Goals Objective: The objective is to predict where coastal bluff top erosion will occur. Methods/Materials Materials and method: (3 boxes, dirt, rocks and three water sources.) three different dioramas of bluffs were constructed. Each having different forms of bedrock, vertical, diagonal and horizontal. Each had six rocks and the same amount of dirt. Water dripped on these dioramas for 24 hours at 10 drops a minute. Results Results: The height of the diagonal diorama was 5.7-cm. For trial one, 2.3 cm depth and 4.5 cm. For the horizontal diorama, height: 2.5 cm, Depth: 1 cm, Width 3.3 cm. For the vertical diorama, height: 5 cm, depth: 4.3 cm, width 5.5 cm. Conclusions/Discussion Conclusion: The horizontal diorama had the least amount of erosion
